Mariazeller sand is a magical sand that children can use to play and build castles indoors. Thanks to its special structure, this flowing sand is very easy to handle. Its fluid properties, adaptability, and smoothness make it a unique product. It can also be used in therapeutic settings.
What you should know and consider is:
The sand can be thermally treated and used for therapy.
Keep in mind that microwaves, for example, heat the sand from the inside, and therefore the sand inside could be hotter than it appears from the outside.
Do not seal the sand airtight. Sand needs to "breathe". The sand is generally dry.
Therefore, no bacteria or similar substances remain stuck to it.
You can't really clean the sand.
However, if you feel you can somehow get the sand cleaner (during cold and flu season),
Then simply spread it out on a baking tray or similar and put it in the freezer over the weekend.
Nothing sticks to the sand – but whatever might have been there is gone after 48 hours at minus 30 °C.
